Impact of Ultrasonic-Assisted Preparation of Water Caltrop Starch-Lipid Complex: Structural and Physicochemical Properties.

This study investigates the effect of ultrasonic-assisted preparation on the structural and physicochemical properties of water caltrop starch-palmitic acid complexes as a function of ultrasound intensity and treatment time. All samples exhibited the characteristic birefringence of starch-lipid complexes under the polarized microscope, and flake-like and irregular structure under scanning electron microscope (SEM), indicating the formation of complexes through ultrasonic-assisted preparation. X-ray diffraction pattern further confirmed the transition from the original A-type structure for native starch to V-type structure for starch-lipid complexes, and the relative crystallinity of starch-lipid complexes increased as the ultrasound intensity and treatment time increased.

Development of micro-nanostructured film with antibacterial, anticorrosive and thermal conductivity properties on copper surface.

A micro-nano sharkskin like film (Cu-MNS-FA) was synthesized on copper surface through chemical etching followed by formate passivation, and its anticorrosive, antibacterial and thermal conductivity properties were investigated. Results show that after 7 d of exposure to nature, Pseudomonas aeruginosa and Desulfovibrio vulgaris seawater, the charge transfer resistance of Cu-MNS-FA is more than three times higher than that of unmodified copper. In particular, in D.

Evaluation of the diagnostic efficiency of fluorescence hybridization for pulmonary tuberculosis: a systematic review and meta-analysis.

Objective: In clinical practice, an accurate and efficient detection approach for pulmonary tuberculosis (PTB) is highly needed. The fluorescence hybridization (FISH) assay for PTB might be a suitable alternative to current tests. However, a systematic assessment of the diagnostic performance of this new approach is not available.

A simple and colorimetric method utilizing cell-free toehold switch sensors for the detection of Chlamydia trachomatis, Ureaplasma urealyticum and Neisseria gonorrhoeae.

Background: Sexually transmitted infections (STIs) rank among the most prevalent acute infectious conditions and remain a major global public health concern. Notable STI pathogens include Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), and Neisseria gonorrhoeae (NG). Early detection and diagnosis are crucial for controlling the spread of STIs.

Pervasive aquatic vegetation organic carbon losses in China's lakes.

One of the major global concerns is to mitigate carbon dioxide emissions to addressing the detrimental impacts of climate change. Aquatic vegetation, as a natural carbon pool, offers a potential solution to such problems. However, a crucial impediment is the absence of comprehensive estimates of its organic carbon storage.
